Comprehensive Range of Welded Pipes & Tubes in Carbon Steel, SS, Duplex, and Nickel Alloys. Certified to ASTM, ASME, API & EN Standards with Options in SCH 10 to SCH XXS and Lengths up to 12m. Custom Orders Accepted for Special Grades, Finishes & Third-Party Inspections.
We are an ISO 9001:2015 certified manufacturer and global supplier of Welded Pipes & Tubes, delivering high-quality piping solutions to key markets including Europe, Russia, Saudi Arabia, Oman, Qatar, and the USA. Our welded products are widely used in industries such as oil & gas, construction, water treatment, energy, infrastructure, and petrochemicals. With a focus on precision engineering, durability, and global compliance, we have earned the trust of clients across international markets through reliable performance and timely delivery.
Our welded pipes are manufactured by transforming flat-rolled steel (coils or plates) into a cylindrical shape, followed by longitudinal or spiral welding depending on the product type. The main welding methods we use include Electric Resistance Welding (ERW), High-Frequency Induction Welding (HFIW), and Submerged Arc Welding (SAW). After welding, the pipes undergo sizing, heat treatment, straightening, surface finishing, and rigorous testing. We offer a wide range of welded products such as ERW Pipes, Spiral Welded Pipes, LSAW Pipes, and Stainless Steel Welded Tubes, tailored to meet diverse application needs.
Our pipes are available in a broad range of materials including Carbon Steel (ASTM A53, A500, API 5L Gr. B/X42/X52), Stainless Steel (ASTM A312 TP 304/316/321/347), and Alloy Steel (ASTM A691). Size availability ranges from ½ inch to 100 inches in diameter, with wall thicknesses from SCH 10 to SCH 160 or as per project-specific customizations. All pipes conform to international quality standards such as ASTM, ASME, EN, API, and DIN. Detailed Mill Test Certificates (MTCs) are provided with every shipment, verifying chemical composition, mechanical properties, and full traceability.
To ensure damage-free and secure global deliveries, we provide export-grade packaging options including wooden boxes, steel frames, plastic-capped pipe ends, waterproof wrapping, and bundle strapping with identification tags. Our welded pipes offer superior features such as excellent weld integrity, corrosion resistance, dimensional consistency, ease of installation, and cost-effectiveness, especially in large-scale infrastructure and structural applications. With a strong presence in global markets and a commitment to quality, we are a trusted partner for clients in Europe, the Middle East, and North America.
